Will one treatment cure my hair loss?

No single treatment cures all hair loss. The dermatologist classifies your hair loss type during consultation, then selects the appropriate combination — drugs, scalp injections, or biostimulators — based on what is actually causing the loss.

Are oral Finasteride and Dutasteride safe?

Both are well studied with extensive long-term safety data. Side effects exist and are reviewed in detail during consultation. Bloodwork is ordered when relevant before prescription, and follow-up is scheduled at 3 and 6 months.

How long until I see results?

Hair grows slowly. Drug therapy typically shows a measurable change in shedding by 3 months and visible density change by 6-12 months. PRP often shows hairline thickening at the 4-6 month mark with the standard 3-session protocol.

Should I do PRP, exosomes, or stem cell injection?

These three are not interchangeable. PRP has the strongest published evidence for androgenetic alopecia. Exosomes and stem cell injection are newer and used as adjuncts. Your dermatologist will sequence them based on diagnosis and treatment goal — not as a fixed package.

Can I start treatment during a short visit to Seoul?

Yes. Diagnosis, prescription, and a first PRP or scalp injection can typically be completed in a single visit. Drug therapy continues in your home country with follow-up via teleconsultation as needed.

Overview

Hair loss treatment in Seoul with scalp diagnosis, density support, PRP, and regenerative options by a board-certified dermatologist in Gangnam.

Best for

progressive shedding
thinning density
scalp inflammation and irritation
patients comparing PRP, regenerative care, and medical guidance

Suited for

patients seeking dermatologist-led scalp evaluation
patients with diffuse or patterned shedding
travelers wanting clear next-step planning instead of vague recommendations

Duration: 30-60 min (consultation + scalp injection visit)
Sessions: Drug therapy daily; PRP × 3 at 4-week intervals, then every 3-6 months
Downtime: Minimal (mild scalp tenderness 24-48 h after injection)
Peak result: 6-12 months for visible density change

Timeline

First 4 weeks
Drug therapy initiated. PRP first session typically performed at the diagnostic visit if appropriate. No visible density change yet — this period is for tolerance and side-effect monitoring.
3 months
Drug therapy: measurable reduction in shedding for most responders. PRP: completion of 3-session loading protocol; early follicle response.
4-6 months
PRP: hairline thickening often visible at the 4-6 month mark with the standard 3-session protocol.
6-12 months
Drug therapy: visible density change for most responders; trajectory established. Maintenance plan adjusted with the dermatologist.
12+ months
Long-term maintenance — drug therapy continued, PRP every 3-6 months when indicated, adjuncts (Botox / exosome / stem cell) sequenced as the diagnosis evolves.

Devices

Drug therapy — Finasteride / Dutasteride / Minoxidil / Spironolactone

Multiple manufacturers (oral and topical formulations)Finasteride 1 mg: U.S. FDA-approved for male AGA (1997). Dutasteride 0.5 mg: South Korea MFDS-approved for male AGA (2009). Minoxidil 2%/5% topical: U.S. FDA-approved for AGA. Oral low-dose Minoxidil and Spironolactone: prescribed off-label with established dermatology evidence.

Key specs

: Finasteride 1 mg oral, daily — selective 5α-reductase type II inhibitor; reduces scalp DHT and slows miniaturisation in androgenetic alopecia. Strong RCT evidence (Kaufman 1998).
: Dutasteride 0.5 mg oral, daily — dual 5α-reductase inhibitor (types I + II) with greater DHT suppression; useful when Finasteride alone is insufficient.
: Minoxidil — topical 5% solution or low-dose oral (0.25-2.5 mg/day, off-label); vasodilator with proposed potassium-channel-opener mechanism.
: Spironolactone — oral, used for female pattern hair loss as an anti-androgen alternative to Finasteride.
: Side-effect profile, bloodwork (ferritin / thyroid / hormone panel where relevant), and follow-up at 3 and 6 months are reviewed at consultation.

Skin Botox — scalp / hairline injection

Botulinum toxin type A (multiple manufacturers)Used off-label for AGA; small-trial evidence (Singh 2017) — adjunct, not primary.

Key specs

: Low-dose botulinum toxin distributed across the scalp.
Proposed mechanism: reduce scalp tension and increase blood flow to follicles.
: Evidence base is smaller than for drug therapy; positioned as an adjunct.
: Generally well tolerated in published pilot studies.

Exosome scalp application

Multiple stem-cell-derived exosome preparationsAdjunct use; evidence is early-stage. Not a substitute for drug therapy.

Key specs

: Extracellular vesicles derived from stem cell culture media.
: Carry signaling molecules (microRNA, growth factors) that may influence follicle stem cell activity.
: Applied topically after microchannel creation (microneedling / fractional laser).
Honest positioning: adjunct, not standalone.

Stem cell scalp injection

Stem-cell-derived preparations (multiple sources)Adjunct use; evidence base smaller and more heterogeneous than drugs or PRP.

Key specs

: Injected into the scalp to stimulate dormant follicle stem cells.
: Useful as part of a combination plan, not as a replacement for proven drug therapy.
: Sequencing and candidacy determined by dermatologist after diagnosis.

PRP scalp injection

Patient-derived autologous platelet-rich plasmaMultiple RCTs and meta-analysis evidence for modest improvement in AGA (Gupta & Carviel 2017 meta-analysis).

Key specs

: Patient's own blood centrifuged to concentrate platelets and growth factors.
: Injected into the scalp at standardised depths.
Typical protocol: 3 sessions at 4-week intervals, then maintenance every 3-6 months.
: Strongest published evidence among the in-clinic regenerative options for androgenetic alopecia.

Process

01
Hair history, shedding pattern, and scalp symptoms are reviewed first.
02
The dermatologist evaluates whether the issue is density loss, inflammation, patterned thinning, or a mixed picture.
03
A plan is built around scalp care, medical support, PRP, or regenerative options when appropriate.
04
Follow-up expectations are discussed because hair outcomes are usually cumulative.

Aftercare

01First 24-48 hours after scalp injection
Avoid vigorous scalp scrubbing, hot showers, saunas, and heavy sweating. Mild tenderness or pinpoint redness at injection sites is normal.
02Week 1
Resume gentle shampooing the day after the procedure. Avoid alcohol-based scalp tonics and aggressive styling products on injection days.
03Drug therapy — ongoing
Take oral medication as prescribed. Report any concerning side effects between visits. Bloodwork follow-up at 3 and 6 months when relevant.
04Long-term
Hair outcomes are cumulative. Treat 6-12 months as the minimum window before re-evaluating the plan. Photographic tracking at each follow-up visit makes the trajectory visible.

FAQ

Is PRP enough for all hair loss types?

No. Hair loss type, scalp inflammation, medical history, and treatment goals all matter before choosing PRP or regenerative options.

Can a traveler start hair treatment in Seoul and continue later?

Yes. That is often the practical approach: specialist assessment first, then a realistic maintenance plan.

Notice

Tell the dermatologist at consultation if any of the following apply.

Pregnancy and breastfeeding (Finasteride, Dutasteride, Spironolactone contraindicated; PRP and most adjuncts deferred)
Active scalp infection or open wounds in the injection field
Bleeding disorders or active anticoagulation without physician clearance (PRP / scalp injections)
Known hypersensitivity to any prescribed medication or component
History of breast or hormone-sensitive cancer — dermatologist review required before anti-androgen therapy

For your visit

Hair care is usually a longer-term project, so Seoul visits often work best as the first specialist assessment plus initial treatment.
Bring any prior diagnosis, medication history, or scalp treatment details if possible.
